Acronym Overload?

The number of digital options at the moment are overwhelming and with many new manufacturers taking an active interest in calling Australia home for their product line, many front line radio users are met with a new suite of technologies and products, let alone abbreviations, acronyms and terminology!

With analogue radio now being modernized by the digital revolution, the choice of technology has never been more confusing.

Historically two-way radio has been the domain of an in-house expert or even a specific department in larger organizations. These were usually radio technicians or engineers who had a strong technical knowledge and industry experience.

In modern times the picture is less clear. Often responsibility for two way radio now rests in the domain of the IT department, this potentially presents a manager with a difficult task when trying to evaluate and select a radio technology platform that will meet the needs of the organisation.

If you are new to the radio communications world and are involved in today’s digital discussions, the following commonly used abbreviations and terminology, may be of some assistance.
